Abstract: The preparation of ceramic pigments using industrial waste, a galvanizing sludge from
the Cr/Ni plating process, as primary source is here reported. The ceramic pigments were prepared
using the common solid state reaction process, investigating the optimal formulation, milling and
firing conditions. The main focus will be given on the synthesis of chrome-tin red malayaite
Ca(Cr,Sn)SiO5 pigment that was fully characterised and then tested in a standard ceramic glaze.
Typical working conditions and colour development will be also reported.
